Method Details

wrap

public static <T> VersionedList<T> wrap(List<T> list)

Wraps a list in a VersionedList instead of copying it. This is useful for cases where a VersionedList is required but strict versioning is not, for example, passing a static list to a ListBox. Changes to the wrapped list obviously don't trigger version changes in the wrapper. Only changes through the wrapper will increment the version.

incrementVersion

protected void incrementVersion()

getVersion

public long getVersion()

Description copied from interface: VersionedObject

Returns the current version of the versioned object.

Specified by:

getVersion in interface VersionedObject<T>

getObject

public List<T> getObject()

Description copied from interface: VersionedObject

Returns the object that is being versioned.

Specified by:

getObject in interface VersionedObject<T>

createReference

public VersionedReference<List<T>> createReference()

Description copied from interface: VersionedObject

Creates a new VersionedReference that can be used to monitor when this object changes.

Specified by:

createReference in interface VersionedObject<T>

size
